What is web optimization?

I am not really familiar about web optimization, but I am willing to learn this thing. Web optimization is a term similar to search engine optimization, but this more unique than any other optimization activities. Actually when SEO focuses on search engines, web optimization focuses on websites. Meaning, if we do SEO on our sites like link building, forum posting, social bookmarks, etc., we can do web optimization in just one thing. We will optimize our sites not in search engines, but within websites. Professional websites are a good example for web optimization. If we can ask the web owners to optimize our respective sites to them, based on the niche of interest, it's up to the owner to decide if he approves it or not.

I hope we learn something on what web optimization is all about.
